ATC210 Dual-Input Bus Converter Integrated Power Conversion and Power Management Solution ATC210 Dual Series | 210 W DC-DC Intermediate Bus Converters File Name: atc210.pdf Rev: 16 Aug 2006 The dual input ATC210 bus converter provides AdvancedTCA (ATCA/PICMG3.0) board designers a compact and rugged solution for generating intermediate bus voltages in a footprint-optimized package. The ATC210 is more than a power converter. It also provides power interface and power management functionality. The power interface functions include ORing, filtering and inrush control, while power management functionality is facilitated by both I 2C serial bus and direct high-speed interfaces. Footprint optimized for high-density ATCA applications Accepts inputs from both -48 V “A” and “B” feeds Power management functions include ORing, inrush control and transient protection

210 W on 12 V Intermediate Bus

6 W on 3.3 V Management Power Bus I2C serial bus interface for monitoring and reporting Programmable alarm thresholds via I2C Bus Hardware alarms via opto-isolators for loss of A or B feeds Comprehensive protection circuitry - current, voltage and temperature RoHS compliant Critical alarms, such as loss of A or B feeds, are hardware-implemented. Other alarms are implemented over an I2C serial bus which is enhanced with an interrupt pin. The solution is provided in a 2.3 x 1.8 inch (59mm x 46mm) footprint and provides an optimized solution for space-constrained systems that employ distributed power architectures. [ 2 YEAR WARRANTY ]
